How Sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures and coral growth per year at locations in the Red Sea. What are the explanatory and response variables? Are they categorical or quantative?

Answer / Step-by-step explanation:

To answer this questions, we first try to understand and the basic terms in the narrative.  This includes

Response variable: is a variable that measures an outcome or result of a study. In summary, we can say response variable are objects that respond to various changes made during an experimentation process.

Explanatory variable: This is a variable that practically explains the causes of changes in the response variables  

So consequentially, if we refer back to the asked question,

EXPLANATORY VARIABLE can be likened to be = Water Temperature

RESPONSE VARIABLE can be likened to be  = Weight

Categorical variables places the individuals into a category, while a quantitative variable is a numerical variable.

So consequentially, if we refer back to the asked question,

Water Temperature = Quantitative

Weight = Quantitative
